Just attach an addEventListener() and you are better off than using an “emulated pause”. Please don’t, Javascript is event-driven. This setTimeout () method mimics the sleep method that’s native in other languages by: Setting a timer in the background when the JavaScript engine executes the setTimeout () function Continuing to run other code as the timer does its countdown Executing the callback function in setTimeout () when the timer reaches zero. In programming languages, the sleep() function waits for a specific amount of time ( few seconds/milliseconds/minutes / or, more) before executing the next line.

Loop and pause until things have been loaded.Pause for a few seconds until the animation has ended.Ever wonder why the developers of Javascript didn’t bother to implement a “sleep” or “pause” function? Definitely not because they have forgotten, but because it does not make sense. But otherwise, none of these are good solutions. If I am forced to choose one – Async timeout.

That’s all for this guide, and here is a small section on some extras and links that may be useful to you.
